First, you can add --launch-agent rsh to the command line and that
will have OMPI use rsh.
It sounds like your remote nodes may not be seeing your OMPI install
directory. Several ways you can resolve that - here are a couple:
1. add the install directory to your LD_LIBRARY_PATH in your .cshrc
(or whatever shell rc you are using) - be sure this is being executed
on the remote nodes
2. add --prefix=path-to-install on your cmd line - this will direct
your remote procs to the proper libraries

Maybe I should also add that the program
my_mpi_executable is locally installed under the same root directory
as that under which openmpi-1.3 is installed. This root directory
is NSF mounted on the working nodes.

Hi Ralph:
Thanks for your prompt response. I am using openmpi-1.3, Suse 10.3.
I installed openmpi-1.3 with the option
./configure --prefix=/where/to/install
and then just
make all install
I thought the default connection mode is rsh, but I had to invoke
ssh-agent, in order not have to enter password one by one. How to
change to rsh?
Thanks,
JO

Could you tell us what version of Open MPI you are using, a little
about your system (I would assume you are using ssh?), and how this
was configured?
Thanks

Hi:
When I execute something like
mpirun -machinefile machinefile my_mpi_executable
I get something like this
my_mpi_executable symbol lookup error: remote_openmpi/lib/
libmpi_cxx.so.0: undefined symbol: ompi_registered_datareps
where both my_mpi_executable and remote_openmpi are installed on
NSF mounted locations.
Any clue?
thanks
JO
